Came across this link, extremely useful info on McKee's including pictures. I believe that entire page consists of Mckees. It includes marriages,deaths,pedigrees,births,etc. Hope the link works for you.
In the surname box type in McKee and click on search
When you get to that page it's the "3rd" one down I believe it says the David McKee Family It begins with
the earliest McKee's and the descendants.
